A new study reveals what goes on in the brain when a person embarks on a musical collaboration project.
Researchers have identified a subpopulation of dopaminergic neurons in the caudal ventral tegmental area that appears to suppress food intake by triggering satiation in mice.
A rare genetic mutation interferes with dopamine transporters in the brain, causing Parkinson's-like symptoms in children.
A new gel that contains levodopa can adhere to nasal tissue. The gel releases levodopa directly into the blood and brain. Researchers say the preliminary data reveals the gel has proven to be effective in animal models.
Fruit flies may use dopamine to learn in similar ways to humans.
The VGLUT protein is more abundant in the dopamine neurons of female fruit flies, rodents, and humans than in males. The finding shed light on why females have greater resilience to age-related dopamine neuron loss and disorders such as Parkinson's disease.
Viewing a subliminal image of their own faces, participants showed an increase in activity in the dopamine reward pathway in the brain. Findings shed new light on the underlying neural processes of self facial recognition.
Researchers have identified novel neurocircuitry between midbrain structures which are modulated by leptin to control eating behaviors in mice.
Dopamine neurons largely rely on their own discharge to determine release rates of the hormone, researchers report.
A recent study found 42% of participants gained, on average, 29 lb of unwanted weight during the pandemic, with people gaining 1.5lb per month. Researchers say a combination of stress, hormones, and dwindling motivation to exercise during the lockdowns may be to blame.
Mouse study reveals elevated dopamine levels preceded hallucination-like events, and artificially boosting dopamine levels induced more hallucination-like events. The behavioral effects could be blocked by administering haloperidol, an antipsychotic which blocks dopamine. The study sheds light on potential new treatments for psychotic disorders marked by hallucinations.
Study identifies genes that become activated in the brain prior to the initiation of severe repetitive behaviors associated with addiction, ASD, and schizophrenia.
